[0023] The working principle of the present invention is as follows: The intake pipe 3 is used to send in the dusty gas, and the outlet pipe 4 is used to discharge the gas after dust removal. During operation, the servo motor 19 outputs a rotational speed in a set state. After the servo motor 19 outputs the rotational speed, multiple dust removal modules perform a station conversion. When the dust removal cylinder bag 13 rotates, the striking shaft 29 rotates relative to the dust removal cylinder bag 13 at a set speed. After the striking shaft 29 rotates, the rubber dust striking rod 31 is used to perform on-line dust striking and ash removal on the foreign dust adhered to the outside of the dust removal cylinder bag 13. By performing on-line dust striking and ash removal on the dust removal cylinder bag 13, on-line self-cleaning dust removal during the dust filtration process of the dust removal cylinder bag 13 is realized, and the high dust removal performance of the dust removal cylinder bag 13 is maintained. After the drive shaft 8 outputs the rotational speed, the reciprocating table 10 performs a reciprocating motion at a set speed relative to the driven rotating seat 11. After the reciprocating table 10 performs a reciprocating motion at a set speed relative to the driven rotating seat 11, the layout angle of the dust removal cylinder bag 13 in the box body 1, the dust striking and ash removal intensity of the rubber dust striking rod 31 on the dust removal cylinder bag 13, and the dust striking and ash removal angle are reciprocally changed, thereby improving the dust removal efficiency and dust removal effect of the dust removal cylinder bag 13. After the reciprocating table 10 performs a reciprocating motion at a set speed relative to the driven rotating seat 11, the tension and straightness of the dust removal cylinder bag 13 can be reciprocally changed. Through the reciprocal conversion of the tension and straightness of the dust removal cylinder bag 13, reciprocating tension dust removal of the dust removal cylinder bag 13 is realized during the dust removal process of the dust removal cylinder bag 13, and then the dust removal effect of the dust removal cylinder bag 13 is improved through the expansion effect and expansion intensity of the dust removal cylinder bag 13. Through the setting of the reciprocating driving member, the lower rotating frame 2 performs an up-and-down reciprocating motion relative to the upper rotating frame 5, and then the tension and straightness of the dust removal cylinder bag 13 are reciprocally changed in the axial direction of the dust removal cylinder bag 13, and then reciprocating tension dust removal of the dust removal cylinder bag 13 is realized during the dust removal process of the dust removal cylinder bag 13. When the dust removal module is in the adjacent position of the intake pipe 3, the upper valve pipe 15 is communicated with the one-way exhaust valve 44, and then the gas in the inner cavity of the expansion bladder 47 is emptied, so that the dust removal cylinder bag 13 can perform dust removal operations. When the dust removal module is adjacent to the intake pipe 3, the gas after dust removal by the dust removal module is discharged through the outlet pipe 4. When the dust removal module is in a position far from the intake pipe 3, high-pressure gas enters the dust removal cylinder bag 13, and then pulse-type backwashing self-cleaning of the dust removal cylinder bag 13 is performed. The pulse self-cleaning period is the same as the interval rotation period of the upper rotating frame 5. At the same time, when the dust removal module is in a position far from the intake pipe 3, the expansion bladder 47 is fully inflated, and then the dust removal cylinder bag 13 is fully expanded. Through the setting of the expansion state of the dust removal cylinder bag 13, the foreign dust adhered to the outside of the dust removal cylinder bag 13 can be detached by physical air support structure expansion, and then the dust removal effect of the dust removal cylinder bag 13 is improved through the expansion effect and expansion intensity of the dust removal cylinder bag 13.
